Pinching sensation in the stomach.

Hi doctors, From yesterday after eating I am feeling pinching sensation in my stomach. Especially below the rib cage and top right region of the belly button to top right region of the belly button. Mostly above the belly button in the upper stomach. Sometimes it feels like lumps are there and while touching them it's painful like pinching. My stomach becomes very bloated when this pinching sensation is there. I felt lumps in the stomach lining when the stomach got bloated. I used to have breathlessness and anxiety because of gastritis. My tummy is bloated now. I have gastritis issues I am taking esomeparasole and sucral o Recently I had stopped sucral o But taking esomeparasole early morning and before dinner. Other medicines don't work and causes breathlessness. I am taking hot citric water in the empty stomach and again I started having tea. I m passing gas very often
